An 89-year-old man is being held in custody in the United States over the murders of hundreds of thousands of Jewish men, women and children during the Second World War.
Johann Breyer, who was born in Czechoslovakia, was arrested at his home in Philadelphia on Tuesday night, accused of serving as a Nazi SS guard at the Auschwitz and Buchenwald concentration camps.
Germany, which issued the arrest warrant for Mr Breyer, is seeking his extradition.
He has previously acknowledged working at Auschwitz, but said that his work there was involuntary. --RTHK
